ALKALINE BATTERIES ARE RECOMMENDED FOR USE IN BOTH UN ITS. AVOID USING RECHARGEABLE BATTERIES.
TO INSTALL / REPLACE BATTERIES IN THE TE MPERATURE TRANSMITTER
(INSTALL BATTERIES IN TRANSMITTER BEFORE INSTALLING BATTERIES IN RADIO­CONTROLLED CLOCK) The transmitter uses 2 x AA,1.5V batteries. To install and replace the batteries, please follow the steps below:
1. Remove the battery cover by pushing down towards bottom of transmitter and sliding cover out.
2. Insert the batteries, observing the correct polarity (see marking inside battery compartment).
3. Replace the battery cover on the unit.
TO INSTALL / REPLACE BATTERIES IN THE RADIO-CONTROLLED CLOCK
The radio-controlled clock uses 2 x AA,1.5V batteries. To install and replace the batteries, please follow the steps below:
1. Insert finger or other solid object in the space at the bottom center of the battery compartment and lift up to remove the cover.
2. Insert batteries observing the correct polarity (see marking inside battery compartment).
3. Replace compartment cover.
DO NOT SET THE CLOCK.
REPLACING BATTERY(S):
For best performance, batteries should be replaced at least once a year to maintain the best running accuracy. Ensure that the batteries used are new and the correct size.
Please help in the preservation of the environment and return used bat teries to an authorized depot.

SETUP:
Alkaline batteries are recommended for use in bo th units. NOTE: Do not set the clock until the outdoor temperature is displayed.
1. Place batteries in the outdoor transmitter first, then into the radio-controlled clock. DO NOT PRESS ANY BUTTONS FOR 30 MINUTES.
2. After 15 minutes both the Indoor and Outdoor areas on your clock should have a temperature showing. If not, remove both sets of batteries, wait 15 minutes and repeat step one.
3. After 15 minutes have elapsed, the WWVB time code reception will automatically start. This reception typically takes 10 minutes in good conditions. If after 10 minutes the WWVB time has not been received, use the “SET” key to enter the set-up mode to manually set the Time, Time Zone and Date (see manual settings below). The clock will continue to search for WWVB each hour between 12am and 6am. When the clock has successfully connected with WWVB, it will override the manually set time and date.
Note: In the event of changing batteries of the unit, ensure that the batteries do not spring free from the contacts. Press any button 20 times with the batteries removed. Always wait at least 10 minutes after removing batteries before reinserting, otherwise start up and transmission problems may occur.
WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the atomic clock. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The atomic clock will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST atomic clock in Boulder, Colorado. A team of atomic physicists continuall y measures every second of every day to an accuracy of ten billionths of a second a day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum. This atomic clock regulates the WWVB transmitter.
After 15 minutes the WWVB tower icon in the clock display will start flashing in the top center of the LCD. This indicates the clock has detected a radio signal and is trying to receive it. When
the time code is received, the WWVB tower becomes permanently lit and the time will be displayed.
If the tower icon flashes, but does not set the time or the WWVB tower does not appear at all, then please take note of the following: Recommended distance to any interfering sources like computer monitors or TV sets is a
minimum of 6 feet (2 meters).
Within ferro-concrete rooms (basements, superstructures), the received signal is naturally
weakened. In extreme cases, please place the unit close to a window and/ or point its front or back towards the Fort Collins, Colorado, transmitter.
During nighttime, the atmospheric dist urbances are usually less severe and reception is
possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.
Note:
In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.), the time can be manually set (please refer to notes on Manual time setting).
FUNCTION KEYS
The radio-controlled clock has four easy to use keys:
SET key : To enter into the set mode for the following functions: time zone, DST
+ key : To toggle between the month and date, alarm and seconds display
To change any values in manual set mode
ALM key : To enter into the alarm set mode To activate/deactivate the alarm SNZ key : To activate the snooze function during alarm To exit manual setting modes
LCD SCREEN DE SCRIPTIONS
The radio-controlled clock's LCD is divided into 2 sections and once the batteries are inserted, all the segments will light up briefly before displaying the information for time, date, indoor and outdoor temperatures.
ON/OFF (daylight saving time), language, hour, minute, year, month, date, weekday, ºC or ºF temperature
Radio reception icon
WWVB time
Indoor temperature
* When the signal is successfully received by the Weather Station, the icon will be switched on. (If not successful, the icon will not be shown in LCD) So the user can easily see whether the last reception was successful (icon on) or not (icon off).
If the signal reception is not successful on the first frequency (915MHz) for 30 seconds, the
frequency is changed to 920MHz and the learning is tried another 30 seconds. If still not successful the reception is tried for 30 seconds on 910MHz. This will also be done for re­synchronization.
MANUAL SETTINGS
Note: If the radio-controlled clock has already successfully received the WWVB time signal and displays the correct time and date, then the Manual settings can be skipped.
After completion of the above described procedures in “Setting-up” the manual setting modes can be entered by pressing and holding the SET key for 3 seconds. The following settings can now be programmed:

TIME ZONE
The time zone can be set between the 0 to –12 hour or Greenwich Mean Time (GMT) range in LCD2. To do this:
1. The time zone (LCD2) will st art f lashi ng (Default setting "-5“). Select the desired time zone by pressing and releasing the + key.
Time zone settings: -12, -11, HAW, ALA, PST, MST, CST, EST, ATL, -3, -2, -1, GMT
2. Press and release the SET key to enter the “DST Settings“.
DST (DAYLIGHT SAVING TIME)
1. The ON digit will start flashing on LCD1. Set the DST ON or OFF by pressing the + key.
2. Press and release the SET key to enter the “Language Settings“.
Note:
The DST default is “ON”, meaning that the WWVB will automatically change the time according to Daylight Saving Time in the spring and fall. For areas that do not recognize DST changes (Arizona and parts of Indiana) turn the DST “OFF”.
LANGUAGE
The weekdays can be displayed in LCD1 with the pre-set languages: (US) English, Spanish (E) and French (F).
1. Set the desired language for the weekday display in LCD1 by use of the + key.
2. Press and release the SET key to enter the mode “Manual Time Settings”.
MANUAL TIME
In case the radio-controlled clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.); the time can be manually set. The clock will then work as a normal Quartz clock.
Note: the time will be displayed with an additional PM for the time from 12:00 noon until 11:59.
1. The hour digits will start flashing on LCD1.
2. Set the desired hours by pressing and releasing the + key followed by pressing the SET key.
